Pod::ToDemo
-----------
Pod::ToDemo allows pure-POD tutorials to write demonstration programs when
invoked directly from the command line. This is an easy way to provide
working, tweakable programs for people who've just read a tutorial.
For example, SDL::Tutorial, the bare-bones Perl SDL tutorial, will write a demo program given the command line:
$ perl -MSDL::Tutorial=sdl_demo.pl -e 1
